Device for transversely correcting guide belt of rotary screen printing machine

Abstract

The invention discloses a device for transversely correcting a guide belt of a rotary screen printing machine. The device comprises a position adjusting roller positioned below the guide belt, wherein the position adjusting roller comprises a roller body and a roller shaft; the roller shaft at one end of the roller body is connected with a driving rod, and one end of the driving rod is connected with a driving cylinder; external splines are respectively arranged on the outer surfaces at the two ends of the roller shaft, two spline rings sleeve the external splines, internal splines matched with the external splines are arranged on the inner surfaces of the spline rings, a bearing sleeves the outer part of each spline ring, and a lifting rod sleeves the outer part of each bearing; the bottom ends of the two lifting rods are respectively connected with two lifting cams, and one of the lifting cams is fixedly connected with the rotating shaft of a lifting motor; the two lifting rods are respectively arranged at the left end and the right end of the guide belt, two photoelectric sensors are respectively arranged on the sides, opposite to the guide belt, of the lifting rods, and the photoelectric sensors are connected with a controller. The device provided by the invention can automatically correct the transverse position deviation of the guide belt in real time, and the fabric printing and dyeing accuracy is improved.

Description

Technical field: [0001] The invention relates to the technical field of textile printing and dyeing, in particular to a lateral deviation correcting device for a guide belt of a rotary screen printing machine. Background technique: [0002] At present, due to machine installation errors and manufacturing errors of the guide belt itself, the guide belt of the existing rotary screen printing machine is prone to deviation during work, which affects the printing quality. When the fabric passes through the cylinder, the color paste in each color cylinder is squeezed by the doctor knife in the wedge-shaped groove, and printed on the fabric through the screen holes. It shows a linear proportional relationship. The greater the mechanical pressure of the scraper on the color paste, the greater the penetration force, but the long-term excessive force will increase the fatigue wear of the conduction belt, and at the same time reduce the tension of the conduction belt and reduce the wea...

AI Technical Summary

Problems solved by technology

like figure 1 As shown, the existing guide belt longitudinal deviation correction device is to install a three-roller alignment device at the bottom of the guide belt, and the swing of the control roller 101 is caused by signals sent by two sets of touch rollers 103 close to the guide belt 102 to make the auxiliary motor run forward or Reverse, so that the guide belt can obtain additional acceleration to adjust the longitudinal position deviation, but this guide belt alignment device has the defect of not being able to adjust the lateral position, and cannot completely and accurately adjust the running position of the guide belt

[0004] The existing guide belt lateral deviation correction device is to set baffles on both sides of the guide belt. When the guide belt deviates from the normal position, the guide belt hits the baffle and is blocked, but this correction method has the following defects: the guide belt and the baffle The contact between the plates will cause friction, which will easily cause the wear of the guide belt and the baffle for a long time, and the equipment will be easily damaged; and the baffle can only prevent the deviation of the guide belt, but cannot correct the offset guide belt to the right position. In the correct position, this will lead to poor use of the rotary screen printing machine
